Loher J Ex nA Series Explosionproof Electric Motor
The Loher J Ex nA Series have a modular cooling design which features double-flow inner cooling for a high power density and a homogeneous temperature distribution.
From the Loher J Ex nA Series, there are 2 versions available:
Mounted air-water heat exchanger (JHWK – roller bearings / JHXK - sleeve bearings)
Mounted air-air heat exchanger (JHRK – roller bearings / JHQK - for sleeve bearings)
Also available for exceptional requirements - such as dust explosion protection.
Corrosion protection using special paint finishes according to the manufacturer's standard or customer's specification.
The motors are available as special version for polar regions down to -40 °C (without pre-heating of the motor) or desert regions up to +60 °C.
Wide range of connection systems for large cable cross-sections, high short-circuit strength or phase-segregated version.
Optimized starting and operating parameters and high efficiency by using copper bar rotors as standard.
All motors have a double flow inner cooling for a high power density and a homogeneous temperature distribution.
Complies with almost all of the user requirements and specifications (no deviation philosophy)
High level of acceptance in the various sectors. For instance, Shell and DOW recommend these motors
Complete project documentation guarantees minimum planning costs
High degree of cost effectiveness and low operating costs as a result of the optimum electrical and mechanical values
High degree of variability and versatility using a welded steel enclosure (to adapt the dimensions, mounted components)
